OPERATION

General

The front panel buttons have different functions when the MCE325 is switched from operating mode to setup mode. Legends on the buttons indicate their operating mode functions; legends under the buttons indicate their setup mode functions. All of the front panel buttons were pre- programmed for a certain type of operation. This is the default configuration. Operation for the default configuration is described first, and is then followed by front panel programming instructions to alter the operation.

Operating Instructions

Momentary/Latching Button action

The channel selector buttons and the MIC ON button feature a special momentary/latching dual- action: if a button is pressed and released quickly it will “latch” (turning “on” if off or turning “off” if on); if the button is pressed and held slightly longer, the action will be momentary and the button will turn off when released. All other buttons are latching-only (press to activate, press to release).

NOTE The latching action can be disabled through the front panel programming.

LED Indicators

LED indicators are provided for each button to indicate current status. The LED can provide up to four indications: continuously off, continuously on, short blink (50% on, 50% off) and long blink (90% on, 10% off).

Channel Selection

Table 3.1 summarizes the operation of the channel selector buttons for the various intercom line configurations. Basically, four-wire intercom lines always use one TALK and one LISTEN button for intercom communication, as do two-wire lines when the station has been programmed for two-channel operation.

When the station is operated in four-channel mode, however, each two-wire intercom line uses only one channel selector button to control both talk and listen, and the MCE325 is pre- programmed so that a channel is activated for both talk and listen when the button is pressed. The
